Although the schematics of Pine A64-LTS and SoPine Baseboard shows both the RX and TX internal delay are enabled, they're using the same broken RTL8211E chip batch with Pine A64+, so they should use TXID instead, not ID. In addition, by checking the real components soldered on both a SoPine Baseboard and a Pine A64-LTS, RX delay is not enabled (GR69 soldered and GR70 NC) despite the schematics says it's enabled. It's a common situation for Pine64 boards that the NC information on schematics is not the same with the board. So the RGMII delay mode should be TXID on these boards.
